In recent years, Curvelet Transform is the most preferred technique for image compression. It is proposed that an efficient and fast image compression scheme based on all level curvelet coefficients with SPIHT (Set Partitioning in Hierarchical Trees).After many passes of coding with SPIHT, it degrades the coding performance.There was a need of a transform that handles two dimensional singularit...

BACKGROUND The most common method of customizing shoe insoles to the shape and surface of the foot is to heat and then mold the materials. The effect of heating on the mechanical properties of these materials is unknown. METHODS The properties of individual and common combinations of insole materials were tested before and after heating. Individual materials tested were soft Plastazote (SP), ...

Eukaryotic cells are continuously subjected to mechanical forces under normal physiological conditions. These forces and associated cellular deformations induce a variety of biological processes. The degree of deformation depends on the mechanical properties of the cell. As most cells are anchorage dependent for normal functioning, it is important to study the mechanical properties of cells in ...

background:  radiochromic film is used for radiation dose measurement, xr-rv3 is used in fluoroscopy and ebt2 film in radiation therapy. the aim was to determine if the dosimetric properties of these two films are comparable in megavolt photon beams. materials and methods: comparison measurements included: calibration curves, heterogeneous phantom dose profiles, and nasopharynx dose distributio...

Hydrous silicate melts appear to have greater compressibility relative to anhydrous melts of the same composition at low pressures (<2GPa); however, at higher pressures, this difference is greatly reduced and becomes very small at pressures above 5GPa. This implies that the pressure effect on the partial molar volume of water in silicate melt ( partial differentialV-H2O/ partial differentialP) ...

Grouted sleeve connections have been widely used in precast construction for joining rebar. In order to study their post-fire seismic performance, grouted connections, which are heated first elevated temperature and then cooled down room temperature, tested under both monotonic cyclic loadings. For comparisons, the same tests also carried out on continuous The failure modes, skeleton curves com...

In practical engineering projects, overconsolidation plays an irreplaceable role in the calculation of silt consolidation settlement. Based on a series systematic tests conducted reconstituted soft clay different cities Guangdong-Hong Kong-Macao Greater Bay Area, behavior under depths was studied. According to these tests, shape curves ratio with depth similar that compression curves. Moreover,...

in the United Kingdom of those days. There was a time when Sir Robert Peel, the Prime Minister was told by a President of one of the then Royal Colleges: "No man who has an academic education ought to practise obstetrics." The same gentleman stated amidst applause in a subsequent meeting: "Obstetrics is no calling for a gentleman". The story in the book tells us how in 1946 in the same kingdom ...

We solve for the effective actions on the Coulomb branches of a class of N = 2 supersymmetric theories by finding the complex structure of an M5 brane in an appropriate background hyperkahler geometry corresponding to the lift of two O6 orientifolds and four D6 branes to M theory. The resulting Seiberg-Witten curves are of finite genus, unlike other solutions proposed in the literature. The sim...

Carbon nanotubes have the potential to construct highly compressible and elastic macroscopic structures such as films, aerogels and sponges. The structure-related deformation mechanism determines the mechanical behavior of those structures and niche applications. Here, we show a novel strategy to integrate aligned and random nanotube layers and reveal their deformation mechanism under uniaxial ...
